Why are fiberglass swimming pools better than Concrete? In North Carolina they cost $20-$30,000 less for installation and most concrete pools require resurfacing and re-tiling about every 10–15 years at a cost of $10,000 or more! Long-term maintenance over 50 years will be at least $50,000 less expensive for fiberglass. Imagine Pools come in many different shapes, sizes and colors which are extremely attractive. Not to mention they have a lifetime warranty. Fiberglass pools have become the standard in pools. #fiberglasspools #leisurepools #poolbuilder #pooldesigner #carync #landscapearchitect #generalcontractor
